KA Design expertise combined with exacting manufacturing deliver a range of un compromised Speed, Slalom and Wave fins. Using XFoil for analysis and McFin for preparing the designs for CNC manufacture, each range of these fins are highly optimized for their intended use. Currently all our fins are built from high density G10 laminate. McFin is the only software that allows for such rapid prototype development. Once the fins get to production, the optimized cutting paths halve the production time compared to the output from generic CAD/CAM packages.

Following on from the sensational KA Speed fins Speed Sailing guru Chris Lockwood and KA Chief designer Andrew McDougall have again combined their talents to create a new benchmark in high performance Slalom Fins. Designed and analyzed using the latest computer software, these fins are a must for any sailor serious about going fast. The precise combination of foil shape and profile produce a super slippery fin with un compromised top end, and like the speed fins they are incredibly forgiving even in rough water minimizing the risk of spinout. All fins are precision CNC Machined from high density G10

The Lockwood/McDougall speed fin series provides uncompromising top end potential in symmetric and asymmetric options. Current top speed by Chris = 47.6 knots for the 500m - fastest GPS time ever. Speed sailing is largely about control, if you can get that with a fin that is also slippery and gets you back upwind easily, you have a speed fin. The KA speed fin is not just about sailing on perfect speed strips, but is designed, like most things that Chris Lockwood and Andrew McDougall have a hand in, to handle the difficult conditions with ease. These fins will help any sailor go faster, we are not yet sure they will do 50 knots, but we are sure they will make going fast possible and and as easy and secure as speed sailing can be. These fins:
- provide great control at high speeds.
- do not let go getting back upwind.
- if they do let go they do not buck you, and will come back easily.
- allows controlled deceleration at the end of the run.
- the swept back angle makes them very forgiving and shed weed.
- and of course are very fast!
They can be used on larger than the usual speed boards in moderate conditions to reduce drag when going broad.
Sizes are 21, 21.5 & 23
Tuttle base only

The KA Wave Series features three models all designed by KA head designer Andrew McDougall in conjunction with the KA international team and shaped using McFin design tools. The foils have a thinner connecting section between the base and tip which has proved to be give the optimum dynamics for wave riding. Built from high density G10 laminate and precision CNC machined, the KA fins are available in 21cm, 22cm & 23.5cm
